The Cincinnati Reds placed Wade Miley on the injured list with a neck strain this weekend. That left them in need of a starting pitcher for Monday’s make up game against the Pittsburgh Pirates. While the move hasn’t officially been made yet, the Reds have announced that left-handed starter Reiver Sanmartin will be called up and take the mound to make his Major League debut.
The Reds acquired Reiver Sanmartin in the trade that also brought them Sonny Gray in January of 2019. At the time Sanmartin has limited experience above Low-A, making two appearances in Advanced-A and one more in Double-A. Since joining the Reds he’s pitched in Daytona, Chattanooga, and Louisville in the past two seasons.
During the 2021 season he began the year in Double-A Chattanooga and made three starts and one relief appearance. He gave up one earned run in 18.0 innings with five walks and 23 strikeouts. He was then promoted to Triple-A where he’s spent the remainder of the season. With the Louisville Bats he made 14 starts and seven relief appearances. In his 82.1 innings he posted a 3.94 ERA, giving up 80 hits, 6 home runs, walked 23, and he struck out 89 batters. You can see his entire career’s stats here, but below we’ve included what he’s done in 2021.
The Reiver Sanmartin Scouting Report
The left-handed pitcher is a fastball, slider, change up pitcher. His fastball has some sink to it and will work in the 89-92 MPH range and touch higher every so often. Both the slider and the change up work in that low-to-mid 80’s range. His repertoire is solid, but nothing really jumps off of the page at you. He’s just not “bad” in any given area. Sanmartin throws strikes with all of his pitches, he tends to mix things up well, he keeps the ball in the yard, and he gets plenty of grounders.
The ground ball rate is actually quite strong, too. His ground ball rate of 54% in Triple-A is the 5th best in the league among pitchers with at least 80 innings pitched. While the comparison isn’t perfect because Triple-A is not MLB, a 54% ground ball rate would be 4th best in the big leagues among pitchers that are qualified for the ERA title this season.
As a left-handed pitcher you would expect him to perform well against left-handed hitters and that certainly holds true. In the minors this season lefties have hit just .196/.274/.268 against him with 11 walks and 34 strikeouts in 124 plate appearances. Right-handed hitters have found a little more success, but the numbers are still in Sanmartin’s favor quite a bit. Righties have posted a .250/.300/.341 line against him in 285 plate appearances with 17 walks and 78 strikeouts.
