Dodgers place reliever Kenley Jansen on disabled list

At this rate, the Dodgers could soon have enough injured closers to outfit an entire division.

They lost a fourth late-inning reliever Sunday when Kenley Jansen was placed on the disabled list with inflammation in his right shoulder. The rookie threw 38 pitches in two-thirds of an inning Monday against Houston and 30 more pitches Saturday night in an inning against Florida.

Dodgers Manager Don Mattingly was annoyed that Jansen did not disclose any discomfort in his arm until Saturday, even though it was an ongoing issue.

“I told him too that you can’t have stuff going on and not tell anybody,” Mattingly said. “You get treatment, you take care of it.”

An MRI exam revealed no structural damage, and Jansen is expected to be reevaluated this week.

With relievers Jonathan Broxton, Hong-Chih Kuo and Vicente Padilla already sidelined by injuries, the Dodgers had to dip into the minor leagues to promote another top pitching prospect.

Five days after calling up Rubby De La Rosa, the Dodgers purchased the contract of Josh Lindblom from double-A Chattanooga. Lindblom, 23, was 1-3 with a 2.96 earned-run average and seven saves for the Lookouts.

A converted starter, the right-hander had 33 strikeouts and 11 walks in 241/3 innings and was holding hitters to a .250 average.

To make room for Lindblom on the 40-man roster, the Dodgers designated reliever Travis Schlichting for assignment. Schlichting was 3-1 with a 6.55 ERA in 18 appearances for triple-A Albuquerque.

See ya

Mattingly was demonstrably upset with Ron Kulpa at the end of the fourth inning after the home plate umpire ejected center fielder Matt Kemp.

What irked Mattingly wasn’t so much that Kulpa ejected Kemp for complaining about called strikes but that the umpire did so as Kemp was walking off the field. Kemp didn’t realize he had been ejected until being told in the dugout.

“I didn’t know you could kick somebody out when you’re not even looking at them,” Kemp said of Kulpa.

Said Mattingly, who was also ejected: “The main thing for me is that Matt is walking away at that point and he’s looking away. I just feel like all [Kulpa] has to do is turn around and walk away and then we have no confrontation.”

Fire recap

It took 41 firefighters 20 minutes to extinguish the blaze that engulfed a storage room in the upper deck of Dodger Stadium on Saturday night, according to Los Angeles Fire Dept. spokesman Brian Humphrey.

The cause of the fire, which forced officials to relocate thousands of fans to other parts of the stadium, remains under investigation. No one was injured.

Mattingly said the Dodgers were not apprised of what was going on during the incident.

“We saw the smoke, and you could smell it,” Mattingly said. “I guess it was assumed it wasn’t too major because nobody came down to say, ‘Hey, we’ve got trouble.’”

Short hops

Padilla, on the disabled list with nerve irritation in his right arm, pitched two scoreless innings in the first game of his rehabilitation assignment with Class-A Rancho Cucamonga. … Left fielder Marcus Thames (strained quadriceps) went one for three with a homer in the second game of his rehabilitation assignment with triple-A Albuquerque. … Mattingly said infielder Juan Uribe, sidelined by a strained hip muscle, could rejoin the Dodgers by the end of the series against Cincinnati that starts Friday.
