Rafael Montero

Montero was outrighted by the Mets after missing all of 2018 following Tommy John surgery. The Rangers signed him to a minor-league deal, and upon his return in late July, Montero looked like a new man. The right-hander averaged 95.8 mph on his fastball -- two ticks above his previous career high -- and threw his changeup more to great results. He struck out nearly seven batters for every one he walked, leading to a top-25 K-BB% among all relievers who threw at least 20 innings. The long ball was an issue and he enjoyed some good fortune with a 95.7% left-on-base rate, but Montero reestablished himself at the MLB level and positioned himself for a key role near the back of the Texas bullpen in 2020. With Emmanuel Clase traded, and given incumbent closer Jose Leclerc's fits of wildness, it's not crazy to think Montero could even find his way into some saves if he can build on last season's success.

Montero posted a 4.37 FIP over 119 innings in 2017 -- more than a run lower than his ERA -- which provided a shred of hope that the former top prospect could still make it as a useful major leaguer. Unfortunately, he didn't get a chance to build on his 2017 season as his 2018 campaign was over before it even got started. After a rough spring, Montero was diagnosed with a complete tear of his UCL on March 22 and was forced to undergo Tommy John surgery. It came as no surprise when the Mets outrighted him after the lost season, with Montero electing free agency. The right-hander inked a minor-league contract with the Rangers, and while that landing spot isn't ideal, he's at least in a situation where opportunity should be present once healthy. If he's lucky, Montero will be cleared to begin a rehab assignment in May.

Hype has surrounded Montero since he first arrived in Queens as a 23-year-old in 2014, but it has yet to all come together for the righty from the Dominican Republic. Montero was used as both a starter and a reliever in 2017, but failed to find his footing in either role. In 18 starts, he compiled a 5.08 ERA over 95.2 innings and was roughed up for a 7.33 ERA over 23.1 innings out of the bullpen. He failed to reach even a 2.0 K/BB in either role and just doesn't seem to have the control necessary to succeed in the majors at this point. The Mets have seemed unwilling to make major moves to bolster their pitching staff, and Montero is just 27 in 2018, so he may still have one more chance to prove he belongs in the majors. The 189 strikeouts in 192.1 innings are alluring, but a lot of that luster goes away once you catch a whiff of the 1.71 WHIP that comes with them.

Having worked him mostly as a starter throughout the minors, the Mets planned to use Montero in that capacity in the majors should they need any reinforcements in their rotation. Though he struggled badly enough that he was demoted from Triple-A Las Vegas to Double-A Binghamton midseason, Montero got his chance this season in the form of three spot starts with the parent club. Though his first two starts were decent, he didn't perform well overall, yielding 14 walks and three home runs over 11 innings as a starter. That was actually better than his performance out of the bullpen, though, as the once highly regarded prospect allowed a .371 batting average against en route to a 9.00 ERA in six relief appearances. Unless injuries hinder it again, it's not clear if Montero will get a look in the rotation this season. His stock has fallen far enough that it would be difficult to count on him even if he is tabbed for spot duty.

Montero’s blazing quick ascent through the minors suggested a level of polish that could’ve yielded the season that unheralded teammate Jacob deGrom ended up having as the NL’s Rookie of the Year. It would have no doubt been a best-case scenario, but the ability to limit walks, stifle home runs, and miss plenty of bats with average or above stuff across the board is what Montero was all about in the minors. He got a couple chances with the Mets, but two of those three skills weren’t present. He walked batters in all 10 of his starts including more than one in eight of them and he allowed homers in each of his first five starts, resulting in a 1.6 HR/9 when it was all said and done. With minor league numbers in line with his past, the MLB struggles suggest more of a learning curve issue as opposed to any sort of skills erosion. The incredible depth of the Mets' pitching could make it tough to find time in 2015 or even make him someone they look to move for some hitting.

Montero continued his rapid rise in the Mets' organization, blowing through Double-A Binghamton to pitch a half-season at Triple-A Las Vegas. Two of Montero's hallmarks are his control and limiting home runs, and each were on full display last year, as he posted a 4.49 K/BB ratio and gave up just six home runs in 155.1 innings. Montero has a low-90s fastball, along with a low-80s slider and changeup, and he can paint the black with each of those three pitches. He likely will open 2014 back with the 51s, but like fellow prospect Noah Syndergaard, he should hit New York by mid-season and profiles to be a future No. 3 starter.
