Top 15 Worst MLB Players of 2015

The 2015 MLB season featured some incredible moments on and off the field. An army of talented rookies made their debuts, Bryce Harper finally turned into the superstar we knew he would become, and Pete Rose became the good guy thanks to his quirky moments on FOX's broadcast during the playoffs.

We saw a light explosion of power with nine players hitting 40 home runs following a 2014 campaign when only one guy reached the mark. Pitchers like Zack Greinke and Jake Arrieta had years on the mound where at times they looked impossible to hit. Two no-hitters from Max Scherzer, 301 strikeouts from Clayton Kershaw, and the Kansas City Royals redeeming themselves after a heartbreaking World Series loss in 2014 to win it all this year were huge in making this season a success.

Unfortunately things weren't great for everyone. Not all players were so successful as some either put together incredibly disappointing seasons while others simply made general managers question why they ever called them up from Triple-A in the first place.

To set a standard for a list of the MLB players who had the worst 2015 seasons, players must have reached a certain amount of at-bats or innings pitched. Position players must have received at least 100 at-bats to qualify for this list. Starting pitchers must have reached 50 innings and relief pitchers need to have logged 20. So for Craig Gentry and his .120 batting average in 50 at-bats or Akeel Morris and his 67.50 ERA in 0.2 innings; they will have to wait for another all-inclusive list for their moment of glory.

Another note, not included will be players who greatly underperformed yet were quality enough players. As horrible as Hanley Ramirez and Pablo Sandoval were this season for the Boston Red Sox, there were plenty of guys that were worse.

These are 15 of the worst MLB players from the 2015 season and why it was a year each of them would like to forget.

15 Omar Infante 

Kim Klement-USA TODAY Sports

Let's get technical for a moment and remain positive, if only briefly. Plenty of negativity is about to follow, so before that, I would like to declare Kansas City Royals' second baseman Omar Infante the best worst player of 2015. Infante was so bad he was the only player on the Royals who never had a significant time leading the All-Star balloting when all of his teammates were receiving an unheard of amount of votes daily. He also lost his job when Ben Zobrist joined the team and Alex Gordon was back from an injury thus ultimately leaving him off of the postseason roster in favor of guys like Raul Mondesi Jr., who had never even played a big league game.

14 Casey McGehee

If they're allowed to take away Comeback Player of the Year Awards then surely Casey McGehee is going to attempt to hide his as it might be snatched up any day now. The veteran third baseman played so poorly for the San Francisco Giants in 2015 that the team decided to release him before the year was through.

13 Mike Zunino

Brad Rempel-USA TODAY Sports

I was very tempted to partner Mike Zunino here with backup catcher Jesus Sucre. However, upon further review, Zunino was much worse given the expectation as the starter. I'm not sure what the issue is with the Seattle Mariners finding a credible catcher and Zunino has been the latest to make it a near automatic out.

12 David Buchanan 

Bill Streicher-USA TODAY Sports

Playing for the Philadelphia Phillies is not nearly as lucrative as it was only a few years ago. Pitcher David Buchanan was one of the casualties of the 2015 season, as the worst team in baseball allowed him to start 15 games for them. Few were very good as he received a nice kick in the pants from opposing offenses all year long.

11 Taylor Featherston

An injury to third baseman David Freese gave Taylor Featherston a chance to make his MLB debut in 2015. While fellow third basemen freshmen like Kris Bryant and Miguel Sano had great years, Featherston falls into the category of having one of the worst. Featherston slashed .162/.212/.247 for the Angels in 154 at-bats. In the field, particularly when playing shortstop, Featherston was not very good either. He committed four errors in only 94 innings for a .932 fielding percentage.

10 Bud Norris 

Marilyn Indahl-USA TODAY Sports

Bud Norris pitched incredibly well for the Baltimore Orioles in 2014. Something must have happened in the offseason as the veteran made a complete 180 degree spin for the 2015 season. While with the Orioles, Norris was 2-9 with a 7.06 ERA. Baltimore was so disappointed with him that they moved him to the bullpen where he continued to struggle. An early August release for Norris was how his career with the Orioles ended before the San Diego Padres decided to recruit him. Norris didn't pitch much better there, going 1-2 with a 5.40 ERA in 20 relief appearances.

9 Dan Uggla 

Mark J. Rebilas-USA TODAY Sports

Are we surprised to see Dan Uggla on any worst lists these days? The fallen second baseman has stopped hitting baseballs and instead is hitting hard times. The Washington Nationals gave him a chance to play for them in 2015, but he didn't come through. In 120 at-bats for Washington, Uggla slashed .183/.298/.300. The hope was he could provide them with decent enough power off the bench, however only two home runs was far below expectations.

8 Ross Detwiler 

Jerome Miron-USA TODAY Sports

Pitcher Ross Detwiler was not saved by a change of scenery in 2015. Starting the season with the Texas Rangers after an offseason trade that brought him to the Lone Star State, Detwiler would eventually finish the year as a member of the Atlanta Braves. Before that though, as a member of the Rangers working both as a starter and reliever, Detwiler was 0-5 with a 7.12 ERA. He had a 1.90 WHIP hurt mostly by the 13 hits per 9 he allowed while with the team. They did release him before too much damage was done, but not before he spread his poor pitching skills into Atlanta.

7 John Mayberry Jr.

Rick Scuteri-USA TODAY Sports

The Texas Rangers probably regret taking John Mayberry Jr. with their first pick in the 2005 draft. More upset by his big league career though could be the New York Mets, who willingly gave him 110 at-bats in 2015 for some unknown reason.

6 Rene Rivera 

Troy Taormina-USA TODAY Sports

You shouldn't expect much out of a career .211 hitter especially when he has mostly been added to the depth chart as the backup catcher. However, after Rene Rivera had a solid season with the San Diego Padres in 2014 while playing in over 100 games for the first time in his career, the Tampa Bay Rays thought he was capable of becoming their number one man behind the plate.

5 Matt Boyd

Peter G. Aiken-USA TODAY Sports

As one of the players the Toronto Blue Jays traded to the Detroit Tigers for David Price, there is some pressure on Matt Boyd to perform well. So far, with both teams, it hasn't gone so well. Combined as a member of the Blue Jays and Tigers in 2015, Boyd went 1-6 with a 7.53 ERA. He also allowed 2.7 home runs per 9 in a rookie year he would soon like to forget.

4 Buck Farmer 

Mark J. Rebilas-USA TODAY Sports

The Detroit Tigers were not short on bad pitchers in 2015. Among them, Buck Farmer was the worst. So far in two short seasons with the Tigers, he remains winless. Somehow, even with a 7.36 ERA in 2015, his career numbers did slightly improve. The Tigers gave him five starts and nine more appearances out of the bullpen to try putting things together. Unfortunately he never did and each time he took the mound, daily fantasy baseball players knew to stack against him.

3 Matt Joyce 

Gary A. Vasquez-USA TODAY Sports

Finding a credible left fielder was tough for the Los Angeles Angels in 2015. Josh Hamilton's drug relapse in the offseason opened up the chance for the recently acquired Matt Joyce to step in and have a great inaugural season for his new team. The result was far different. In 247 at-bats with the Angels, Joyce slashed .174/.272/.291 with only 5 home runs. For a guy who should hit 15-20 a year, this was incredibly disappointing.

2 Nick Franklin 

Kim Klement-USA TODAY Sports

Can we officially call Nick Franklin a bust? He was drafted in the first round of the 2009 MLB Draft by the Seattle Mariners and in 2015 put up statistics for the Tampa Bay Rays that even the most loving father couldn't appreciate. Just barely qualifying for this list with 101 at-bats, Franklin slashed .158/.213/.307 while also delivering below average defense. At shortstop, one of the positions he played at frequently, he had only a .909 fielding percentage.

1 Drew Stubbs 

Chris Humphreys-USA TODAY Sports

If all you saw of outfielder Drew Stubbs was his 2015 performance, you would wonder why he is allowed to play professional baseball. At one time a classic power hitter, minus the power and mostly just the slew of strikeouts, Stubbs hit a new low this past season. While with the Colorado Rockies, Stubbs slashed just .216/.286/.431 in 114 plate appearances. The worst part of it was that he struck out 50 times.

Stubbs was eventually released by the Rockies in late August only for the Texas Rangers to regretfully pick him up. Down the stretch, Stubbs went just 2 for 21 for the Rangers with 10 strikeouts. It gave him an overall slash line for the year of .195/.283/.382 and 60 strikeouts in only 123 at-bats for a dreadful strikeout per at-bat ratio. If there’s any question as to why Stubbs is at the top of this list, a strikeout in just about every second at-bat is hard to top.
