Ramirez, 24, enjoyed an excellent rookie season with the Mariners in 2012 when he worked to a 3.36 ERA with 7.3 K/9, 1.8 BB/9 and a 40.4 percent ground-ball rate in 59 innings, making eight starts and eight relief appearances. While stats like FIP, xFIP and SIERA all pegged him for a slightly higher mark — in the 3.55 to 3.75 range — it was a promising debut for a player that had ranked as the organization’s No. 13 prospect (per Baseball America) in the previous offseason.
However, Ramirez has fallen on hard times since that impressive debut; over the past two seasons, he’s recorded just a 5.12 ERA that unfortunately lines up nearly exactly with his 5.11 FIP. Ramirez’s strikeout and ground-ball rates have remained similar, but he’s seen his control take a step back, averaging 3.7 walks per nine innings in that time while becoming increasingly homer-prone.
Ramirez was out of Minor League options, meaning he would have been required to clear waivers before the Mariners could send him outright to Triple-A. The Rays then appear likely to keep him on the 25-man roster and hope for better results from Ramirez at the back of an injury-plagued rotation. In addition to Matt Moore, who is recovering from Tommy John surgery, the Rays will also open the season without Drew Smyly at full strength. Alex Cobb and Alex Colome have both been slowed by injuries this spring as well, which has led to a well-known search for rotation depth in Tampa.
Montgomery, who turns 26 in July, was once one of the crown jewels of a vaunted Royals farm system, but his career stalled upon reaching the Triple-A level. Montgomery posted ERAs of 5.32 and 6.07 in his first two years reaching that level, and he’s struggled at lower levels since. All told, he has a 4.98 ERA with 7.0 K/9 against 3.9 BB/9 in parts of four seasons at Triple-A.
The Rays acquired Montgomery from the Royals in the James Shields/Wil Myers blockbuster in hopes of revitalizing his career. However, while his numbers improved a bit — 4.29 ERA in 25 starts at Triple-A last year — he’s yet to show the promise that made him the No. 36 overall pick in the 2008 draft and one of the game’s top prospects from 2010-12. In their last scouting report on him, following the 2012 season, BA wrote that Montgomery began experimenting with a lower arm slot that caused his velocity to dip from the 92-93 mph range to the 88-90 mph range, adding that left-handed hitters were too comfortable against him. Montgomery is a reclamation project for the Mariners, but although he’s on the 40-man roster, he, unlike Ramirez, has an option remaining and can therefore hope to rediscover himself in the Minors in 2015.
