Tyler Glasnow continued his march toward pitching in the Dodgers’ opening series, pitching into the fifth inning in a 4-1 win over the Arizona Diamondbacks on Tuesday at Camelback Ranch.

Glasnow allowed a home run on his second pitch of the game, to Diamondbacks outfielder and leadoff batter Jordan Lawlar, but was otherwise stingy. He gave up only one more hit (a single) and a walk, and struck out five, and was so efficient that he even faced (and retired) one batter in the fifth inning to get to his pitch limit. Glasnow needed 60 pitches to complete his 4 1/3 innings, only nine more pitches than he used in 2 2/3 innings last Wednesday against Mexico.

He’s the first Dodgers pitcher this spring to pitch more than three innings in a Cactus League game.

The Dodgers have their first off day of camp on Wednesday (with another coming on March 19), then are back at Camelback Ranch on Thursday night against the Cincinnati Reds (6:05 p.m., SportsNet LA).
