Blue Jays vs Mariners: Tonight's Lineup - Game Preview

Kevin Gausman came away with a no-decision in a 5-3 loss to the Guardians in his last outing.

Scattering one hit and one walk over six scoreless innings. He struck out nine.

The veteran right-hander put together perhaps his best performance of the season, generating 32 called or swinging strikes among his 94 pitches (66 total strikes), but he missed out on his third win of the year when the Blue Jays' bullpen melted down late.

The quality start was Gausman's fourth in seven trips to the mound, and he'll take a 3.83 ERA, 0.93 WHIP and 37:12 K:BB through 40 innings into tonights contest against Seattle.

Luis Castillo gets the ball tonight for the Mariners. Castillo pitched six innings in a no-decision against Texas in his last outing, allowing one run on four hits and two walks while striking out two batters.

Though he induced just two whiffs and fanned a season-low two batters, Castillo was sharp against the Rangers, as he didn't allow any extra-base hits and threw 58 of 88 pitches for strikes.

Since allowing nine runs over 9.1 innings in a two-start span in mid-April, the veteran hurler has bounced back with two straight quality starts during which he has yielded just one run over 12 frames.

The excellent pair of outings has brought Castillo's ERA back down to 3.29, though his 30:16 K:BB over 38.1 innings is mediocre.
