Mariners Lineup: Raleigh gets night off from catching

The Seattle Mariners are giving Cal Raleigh a day off from his duties behind the plate on Tuesday night.

Mariners call up rookie reliever, DFA Casey Legumina

Raleigh is still in the lineup hitting in his usual spot at No. 2 in the batting order, but Mitch Garver will be at catcher and bat seventh while Raleigh is the designated hitter as the M’s take on the Athletics and left-hander Jacob Lopez.

With Raleigh getting the start at DH, Rob Refsnyder is starting in right field for just the third time this season.

Below is a full look at the Mariners’ lineup, which includes Refsnyder in the leadoff spot.

Shortstop J.P. Crawford is batting sixth for the second time this season. Additionally, Leo Rivas is getting another start at third base while Brendan Donovan is on the 15-day injured list due to a left groin strain.

Right-hander Luis Castillo takes the mound for Seattle in search of a bounce-back outing following a rough three-start stretch. After pitching six scoreless innings against the Yankees in his season debut, Castillo has allowed 15 runs (11 earned) over 12 1/3 innings over his past three starts.

Castillo faced the A’s twice last season, posting a 1-1 record and 2.25 ERA with three runs allowed over 12 innings. He has a career 5-3 record and 3.02 ERA in nine starts against the Athletics.

The Mariners continue their three-game series against the Athletics at 6:40 p.m. on Tuesday. Radio coverage on Seattle Sports 710 AM and the Seattle Sports app starts with the pregame show at 5:30 p.m.
