Most frustrating players of the 2017 MLB season

Projected as an ace when he was taken third overall in the 2011 draft, the Indians are still waiting for Bauer to shine. He's missing bats at will with more than 11 strikeouts per nine innings this year, but his ERA stands at 5.83 through 11 starts due to the long ball.

Blanton agreed to a contract late in the offseason for the relief-needy Nats. It's been a poor get for Washington, as Blanton allowed 13 earned runs in only 12.1 innings before going on the DL with a shoulder injury.

Minnesota deserves credit for sticking with its top prospect while he's struggled early this year. Buxton is hitting only .201-2-10 with nine steals and 60 strikeouts in 173 plate appearances. He has shined defensively in center field, however.

All good things must come to an end, which could be the case for the 44-year-old Colon this season. After signing a one-year, $12.5 million contract with Atlanta in the offseason, Colon has allowed a league-worst 51 earned runs in 59 innings and is now on the DL.

Corbin struggled last season but looked like he'd bounce back after a strong spring. That hasn't been the case, as Corbin still can't keep the ball in the park. He's allowed 14 homers in 66.1 innings, resulting in a 5.43 ERA.

Dyson opened the season as the Rangers' closer, but it didn't take long for him to lose the job. After allowing 20 earned runs in only 16.2 innings, the Rangers designated him for assignment in early June and just recently traded him to the San Francisco Giants.

Escobar is in a walk year, but he's not doing himself any favors. The shortstop is hitting an atrocious .177-0-13 with a pitiful .424 OPS and 5/47 BB/K in 233 plate appearances. It's getting to the point that the Royals can't afford to keep playing him.

The streaky Espinosa hit a career-high 24 home runs with the Nationals last season, but he ended the season hitting .172-6-23 in 269 plate appearances after the break. Those struggles have carried over to Anaheim this year, where he's hitting .150-5-18 in 179 plate appearances.

Gausman became Baltimore's ace last year, but he's regressed early this season. Control issues and continued inability to keep the ball in the park have resulted in a 5.86 ERA through 13 starts.

Gordon is in the second year of a four-year, $72 million contract that the Royals have to regret. He's hitting just .177-1-11 through 51 games.

Grichuk's offensive struggles caused the Cardinals to demote him to Single-A. The 25-year-old was hitting just .222-4-19 in 46 games.

Hammel signed a two-year contract with the Royals late in the offseason. The move hasn't helped Kansas City, with Hammel posting a 5.93 ERA through 11 starts.

Harvey has been frustrating both on and off the field in 2017. He has a 5.43 ERA in 11 starts, returning from thoracic outlet syndrome, and he was also briefly suspended for failing to show up to the ballpark.

Marte failed to make the Arizona roster out of spring training while battling for the starting shortstop job after seeing significant playing time in Seattle over the last two years. He's yet to get a call-up this season, though he's hitting .379 at Triple-A Reno.

After rebounding between Tampa Bay and San Francisco last season, this season has been a struggle for Moore. He has a 5.22 ERA through 12 starts for the Giants.

Odor became a star last season, hitting 33 home runs for the Rangers. This season has been a different story, as he's hitting just .204-8-24 through 58 games.

Quintana earned the title of Chicago's ace after the team traded Chris Sale in the offseason. He hasn't lived up to it with a 5.30 ERA and league-leading seven losses in 12 starts.

Richards opted for rehab instead of Tommy John surgery last year and went through spring training healthy. Unfortunately, he lasted only one start during the regular season before a biceps injury sidelined him.

Is this the end of the road for K-Rod? The former closer lost the job in Detroit early this season and has a 7.36 ERA in 20 appearances.

Salazar had elbow issues late last season and was demoted to the bullpen by Cleveland recently. He has an impressive 12.6 strikeouts per nine innings but hasn't been able to keep the ball in the park, resulting in a 5.40 ERA.

Acquired from the Cubs for Wade Davis in the offseason, Soler continues to be one of the most frustrating hitters in baseball. He's shown big-time power in the past but started the season on the DL with an oblique injury and has now been demoted to the minors after hitting only .164-1-3 through 65 plate appearances.

Tanaka has allowed an AL-worst 48 earned runs in 66 innings for the Yankees with a staggering 17 homers allowed. It's quite a regression for a pitcher who has never had an ERA worse than 3.51 in the majors.

Teheran entered the year as Atlanta's ace after posting a 3.21 ERA in 30 starts last season. Unfortunately, he's regressed with the opening of Atlanta's new ballpark this season, posting a 5.40 ERA and struggling with walks.

A consistent offensive player over the last three years for Oakland, Vogt is hitting only .222-3-13 through 146 plate appearances. His poor play could cause the A's to consider some of their catching depth for more playing time.

Zimmermann's five-year, $110 contract looked like a nightmare after the first year, and nothing has changed this season. He has an atrocious 5.98 ERA through 11 starts, allowing 16 home runs in 61.2 innings.
