The Dodgers have summoned right-handed pitcher Zach Neal from Triple-A Oklahoma City prior to tonight’s game against the Arizona Diamondbacks. Right-hander Josh Fields was placed on paternity leave to make room for Neal on the Dodgers’ 25-man roster.

The Dodgers emptied their bullpen in a 15-inning, 8-7 loss that began Monday and ended after midnight Tuesday in Phoenix. Wilmer Font shouldered the brunt of the load, pitching the final 4 1/3 innings. He threw 74 pitches in that game after throwing 31 pitches the night before in Los Angeles.

To accommodate Neal on the 40-man roster, the Dodgers designated right-handed pitcher Jesus Liranzo for assignment. Liranzo was acquired from the Baltimore Orioles on Sunday in a trade for minor league pitcher Luis Ysla.

The Dodgers signed Neal, 29, as a free agent in January. In 30 major league games, all with the Oakland A’s, Neal is 2-4 with a 4.89 earned-run average. He spent time in the bullpen and the rotation in Oakland, and was expected to begin the season in the rotation at Oklahoma City. The Pacific Coast League season begins Thursday.

Neal’s pitch-to-contact profile is unusual; he’s struck out only 37 batters in 84-2/3 major-league innings. But he has walked only seven batters, and can use a sinker and changeup when effective to induce weak ground balls.

Neal appeared in three Cactus League games with the Dodgers, allowing nine hits and four runs (all earned) over five innings.

Fields and his wife, Brittney, are expecting their first child.
