Chafin signed a one-year, $1.945 million contract with the Diamondbacks on Friday to avoid arbitration, Robert Murray of The Athletic reports. Chafin had a good year out of the bullpen for the Diamondbacks in 2018, posting a 3.10 ERA, 1.34 WHIP and 9.7 K/9 across 49.1 innings. The 28-year-old's 2.65 FIP also suggests some room for improvement as he should once again serve as a situational left-hander for Arizona.
Chafin was credited with his 13th hold of the season after retiring the lone batter he faced in Sunday's 5-2 win over the Mariners. Chafin was the first reliever summoned from the bullpen after starter Zack Greinke exited with two outs and two runners on in the top of the seventh inning. As per usual, Chafin aced the lefty-on-lefty matchup with Robinson Cano, inducing an inning-ending groundout in five pitches to end the Seattle threat. Chafin owns a 2.13 ERA and 9.4 K/9 for the season, but the impact of that production has been limited due to his low innings count, as he's frequently been called upon to face only one or two hitters over his 61 appearances.
Chafin was reinstated from the paternity list Friday. Chafin missed three days while on paternity leave. To make room for him on the roster, Chris Owings was optioned to Triple-A Reno.
Chafin was placed on the paternity list Tuesday. He must miss one game and may not miss more than three games, so he will return to the Diamondbacks' bullpen later this week. Silvino Bracho was recalled from Triple-A to take his spot in the bullpen.
Chafin retired two of the three batters he faced in Sunday's 6-1 win over the Rockies. Chafin allowed a leadoff single to Charlie Blackmon in the top of the ninth inning, then induced a double-play ball before giving way to Silvino Bracho, who got Nolan Arenado to ground out to end the game. Manager Torey Lovullo typically limits Chafin's usage to lefty-on-lefty matchups, which has helped the 28-year-old attain a bullpen-best 1.51 ERA this season.
