After posting a .282 on-base percentage and .230 slugging percentage with Indianapolis in April, Luplow hit .310/.386/.620 in May and .320/.409/.500 in June. Since May 1, he has a .412 OBP, a .330 average and eight home runs.
In 87 plate appearances in the majors last season, Luplow hit .205/.276/.385 with three home runs.
Holmes started Wednesday in place of the injured Joe Musgrove. He allowed four hits and five runs in 2u2153 innings against the Los Angeles Dodgers.
