8) David Phelps (8.86)

David Phelps is a 6’2″, 200 lb. right-handed pitcher from St. Louis, MO. He’s currently on the 60-day DL with the Seattle Mariners, but he used to be one of ours.

Phelps was chosen in the 14th round of the 2008 draft by the New York Yankees, and made his way up through their system. After making his major league debut with them in 2012, he went 15-14 with a 4.21 ERA over 87 total appearances in three seasons. After the 2014 season, the Yankees traded him with Martin Prado for Garrett Jones, Domingo German, and Nathan Eovaldi.

Phelps joined the Miami Marlins rotation for most of the 2015 season. He started 19 times and came out of the bullpen four times, totaling 112 innings. He struck out only 77 batters, earning a 4.50 ERA and a 1.36 WHIP. Phelps also allowed a .272/.325/.404 slashline for the season, which makes his 2016 season so much more impressive.

In 2016, Phelps was moved primarily to the bullpen, starting five times but making 59 relief appearances. In 86 2/3 innings, he struck out 114 batters, with a 1.142 WHIP, a 2.28 ERA, and a 7-6 record. He also kept opponents to a .197/.288/.294 slashline. His 2.6 WAR for the year ranked second on the club for pitchers, behind only Jose Fernandez. His 11.8 whiffs per nine innings in most other seasons would be good enough to lead the Miami Marlins. During this campaign, it was only third best on the team. The 2016 team was blessed with four fireballers who averaged over 10 K/9. We will get to the other three later in this slideshow.

Phelps came out of the pen 44 times in 2017 for the Florida Marlins. He didn’t make any starts, and struck out 51 in 47 innings. He had a 1.340 WHIP and a 3.45 ERA, and batters slashed .243/.323/.376 off of him. Prior to the trading deadline, the Seattle Mariners parted ways with Brayan Hernandez, Pablo Lopez, Brandon Miller, and Lukas Schiraldi for Phelps.

Since leaving the Marlins, Phelps has pitched 8 2/3 innings for the Mariners, striking out 11 and allowing three runs. He’s currently out for right elbow UCL construction.
