The left-hander is 9-5 with a 4.06 ERA entering Thursday, according to the Associated Press game preview. Phillips, a right-hander, is 5-6 with a 3.45 ERA. Boyd gives Chicago a chance to change the pitching tone after Kevin Gausman limited Miami to two runs in 5 2/3 innings Wednesday but still received no win.
The first two defeats also put pressure on Chicago's hitters to produce before the late innings. Wednesday's tying swing was the Cubs' main answer to Miami's scoring; Tuesday's 12-inning game lasted long enough for a bullpen breakdown to decide it. Seiya Suzuki has 25 home runs and 85 RBIs this season, while Pete Crow-Armstrong has four homers in his past 10 games, according to the AP preview. The Cubs have power available, but they need to turn it into runs against Phillips and Miami's relievers.
