De La Rosa pummeled as former D-backs pitcher Bolsinger leads Dodgers to victory: By the Numbers

The Arizona Diamondbacks’ starting staff is starting to become a cause for concern.

A day after the New York Mets hit four home runs off Josh Collmenter, Rubby De La Rosa struggled mightily against the Dodgers in Los Angeles.

After giving up three singles and a run in the first inning, the Arizona starter seemed to settle down, keeping the Dodgers scoreless over the next two frames.

However, the right-hander became unraveled in the fourth, giving up a whopping five runs in the frame, capped by a Jimmy Rollins three-run homer.

De La Rosa once again allowed a three-run shot the following frame, this time by Andre Either, and the Dodgers enjoyed a nine-run lead just five innings into the contest.

On the other side of the coin, Arizona’s bats were quiet for the second straight day, as ex-Diamondback Mike Bolsinger baffled his former team, keeping the visitors scoreless until the sixth inning.

Los Angeles emerged with a resounding 9-3 win in the series opener, improving to 33-25, the best mark in the National League West. Bolsinger took the win to boost his record to 4-1, while De La Rosa fell to 4-3.

The two clubs will square off again Tuesday in the second of a three-game set.

Here’s a look at Monday’s blowout at Dodger Stadium, by the numbers:

2.08

For a guy who had a 1-6 record and 5.50 ERA in his rookie year in Arizona, the Dodgers’ Bolsinger boasts a 2.08 ERA through 11 starts this year. The right hander went seven innings against his former club, allowing just three hits and two earned runs while walking two and striking out eight in 94 pitches.

3

On the bright side, in relief of De La Rosa, right-hander J.C. Ramirez had his longest and best outing of the season, going three full innings while striking out one and not giving up a single hit or run. The second-year pro dropped his ERA to 4.11 with his performance out of the ‘pen.

5 (part I)

After collecting just 28 hits in a four-game series against the Mets, the Diamondbacks recorded just five for the second straight night, two of which came in the final inning off Dodgers reliever Josh Ravin.

5 (part II)

Ender Inciarte has been fairly hot at the plate recently. The outfielder recorded two of the Diamondbacks’ five hits Monday, as well as one of their three runs scored. The second-year pro has hit safely in 10 of his last 11 contests, including the past five in a row. He’s now batting .290 after his 2-for-4 performance in the loss in L.A.

6-20

The Diamondbacks fell to 6-20 against their division rival over the past two seasons, a winning percentage of .231. That record includes a 2-5 mark this season.

9

De La Rosa’s nine runs allowed were by far a career worst, and they tied Collmenter (May 11 against Washington) for the most surrendered by a D-backs pitcher this season. After recording his first complete game of the year on May 18, De La Rosa has given up a total of 24 runs in his last four starts, with six innings being his longest outing in that span.

10

Jake Lamb got a seemingly meaningless hit in the ninth inning, but it drove in the D-backs’ final run of the night, giving him 10 RBI on the season. More importantly, the single marked the first hit and RBI for the third baseman since he came back from the disabled list Saturday.

11

Chris Owings’ career-best 11-game hitting streak has come to an end. The second baseman went 0-for-4 Monday with three strikeouts, seeing his batting average drop to .245. Yasmany Tomas also had a mini-streak going — five games — which came to an end in the loss. Tomas, who started in right field, went 0-for-3 Monday, with his batting average dipping to .331.

13

One of the few highlights of the D-backs’ offense was A.J. Pollock’s sixth-inning double off Bolsinger, which drove in two. The center fielder’s 13 doubles are tied with Paul Goldschmidt for the team lead, and his 27 RBI are tied for second with David Peralta. The 27-year-old Pollock has hit safely in eight of his last nine games, and he’s now batting .321.

14

A day after Collmenter took the team lead for home runs allowed, De La Rosa took it right back, giving up his 13th and 14th homers of the year. The first-year Diamondback actually lasted five innings on the night, giving up 10 hits while walking one and striking out four in 96 pitches. His ERA ballooned to 5.84 with the forgettable outing.
