When Joey Lucchesi pitched into the seventh inning Monday night against the Rockies at Petco Park, it marked a couple of milestones for the Padres.

• It was the first time in Lucchesi’s Major League career that the 25-year-old left-hander completed seven innings.

• And it was the first time in 18 games this season that a Padres left-hander pitched seven innings.

But the results were not what either the Padres or Lucchesi had desired in the 5-2 loss. Lucchesi gave up two runs in the seventh on a pair of hits, including a leadoff homer by Ian Desmond, who earlier had hit a two-run double against Lucchesi.

After opening the season with 10 1/3 scoreless innings -- with seven hits and three walks against 13 strikeouts -- in his first two starts, Lucchesi has allowed 12 runs on 14 hits (including two homers Monday night) and four walks with only eight strikeouts in 11 innings.

First two starts, 0.00 earned run average and a 0.986 WHIP. Second two, 9.82 ERA and a 1.636 WHIP. Overall -- 5.06 ERA and a 1.313 WHIP.

Notebook
• Right fielder Franmil Reyes’ four home runs this season have come over his last eight games and in a span of 23 at-bats. He is riding a five-game hitting streak (6-for-17) with three homers and four RBIs with two walks. He has gone 8-for-23 after a 2-for-22 start, raising his batting average from .091 to .222. Reyes also has six walks against only eight at-bats.

• Shortstop Fernando Tatis Jr. went 2-for-4 Monday night to extend his hitting streak to five straight games (8-for-18) with a double and two home runs and five RBIs. Monday was the first time in the 20-year-old’s 18-game career that he had two hits in back-to-back games. Tatis Jr. leads the Padres in both homers (five) and RBIs (11).

• Left fielder Wil Myers, who is one of four Padres with four homers, hit the 100th of his career Monday night -- a 428-foot shot to the right side of the batters’ eye in center.

• Third baseman Manny Machado (6-for-19) joins Reyes and Tatis Jr. with an active, five-game hitting streak. Machado is also in the four-homer club with Myers, Reyes and Hunter Renfroe.
