Puig set to showcase power in Home Run Derby

DETROIT -- Dodgers outfielder Yasiel Puig said he will participate for the National League in the Gillette Home Run Derby.

Puig will be ready to take aim at Target Field at 5 p.m. PT on Monday night on ESPN, and in Canada on Sportsnet.

Puig said he accepted the invitation of captain Troy Tulowitzki.

Puig won a starting spot in the NL All-Star lineup by finishing third in fan voting for outfielders. It is the second-year Puig's first All-Star appearance.

Puig had 12 home runs entering Tuesday's opener vs. the TIgers, although he went the entire month of June without hitting one.

Manager Don Mattingly said he wasn't concerned about the competition compromising Puig's swing.

"Watch him in batting practice and he's launching balls all the time," Mattingly said. "I don't think it's that big a deal."

There is one unclaimed spot in each league. Those announcements will come Thursday.

A new format has been installed, as the five players from each league will receive seven outs instead of the usual 10 in the first round. The player who hits the most homers in each league will receive an automatic bye to the third round (semifinals). The next two players from each league with the most homers will square off against one another in a head-to-head matchup in the second round (seven outs), with the two winners advancing to the semifinals against the league's top seed (again, with seven outs).

The final round will also consist of seven outs, and, if necessary, the first tiebreaker would allow each of the two remaining participants three swings apiece.

If you can't wait for the actual Derby, the MLB.com Home Run Derby mobile game is a good way to immerse yourself in the action immediately, with Target Field serving as the setting. The game is available for download on the Apple App Store and Google Play. New for 2014 is Multiplayer Derby Mode, Achievements and Objectives.

Hip injury forces Beckett to disabled list

DETROIT -- The Dodgers placed starting pitcher Josh Beckett on the 15-day disabled list with left hip impingement syndrome on Tuesday and recalled reliever Pedro Baez from Triple-A Albuquerque.

Beckett flew to Los Angeles, where he had an MRI and received a cortisone injection. The Dodgers did not give a timetable for his return, but hip impingements often lead to torn labrum, which can require surgery to correct.

Beckett, despite pitching five scoreless innings on Sunday in Colorado, had to leave the game one inning after feeling a twinge in his left hip while running the bases. The right-hander said the hip has been increasingly troublesome as the season has progressed.

"It's been harder and harder for him each start," said manager Don Mattingly. "We hoped to get him to the break to get extra rest."

Management is hoping that a week off now, plus another week off with the All-Star break, will allow the inflammation to reduce and Beckett to return to the rotation.

Mattingly indicated that Beckett's scheduled Saturday start could be taken by Paul Maholm or Red Patterson.

Maholm is 1-4 with a 5.50 ERA in seven starts this season, mostly when Clayton Kershaw was on the disabled list. He has been in the bullpen since the middle of May.

Patterson allowed one run in 4 2/3 innings in his only start for the Dodgers in a doubleheader at Minnesota. He has been pitching for Albuquerque on the same day as Beckett has for the Dodgers.

Beckett, 34, has enjoyed a remarkable comeback this season after missing nearly all of 2013 with thoracic outlet syndrome, which required surgery to remove a rib that was compressing a nerve. He is 6-5 with a 2.26 ERA and 1.03 WHIP, the second best of his career.

Baez was recalled for one game earlier this year, May 5 at Washington, and allowed two runs on two hits in one inning of relief in his Major League debut.

Crawford could return to Dodgers this week

DETROIT -- Carl Crawford was set to complete his Minor League rehab assignment with Triple-A Albuquerque on Tuesday night.

After completing the assignment, the outfielder will fly to Los Angeles on Wednesday and could be activated as soon as Thursday.

Manager Don Mattingly didn't rule out Crawford's return for the Dodgers' final series at home before the All-Star break against San Diego.

Crawford has been on the disabled list since May 27 with a sprained left ankle. His return will again complicate the lineup, as Matt Kemp has started 37 games in left field since Crawford was injured. The Dodgers are 21-16 with Kemp in left field, and 18-17 with Crawford.

Dodgers' All-Star teacher finalist announced

DETROIT -- Isagani Celzo, a math instructor at the School of Social Justice in Huntington Park, has been selected by fans to represent the Dodgers in the "Target Presents PEOPLE All-Star Teachers" campaign, which celebrates current and retired teachers who make an impact on the lives of their students and communities.

Celzo earned an academic scholarship while working as a janitor and graduated magna cum laude with a degree in mathematics at age 20. A National Board certified math teacher, he is a founding member of the School of Social Justice, where he teaches geometry and AP calculus.

To bolster mathematics achievement, Celzo analyzed student data and designed the Predictor Model, a statistical correlation, which is instrumental in the school's higher CAHSEE passing rate. His students' 2013 state assessment scores ranked the Best CST Summative HS Math out of 71 LAUSD-ISIC high schools.

Celzo's focus on closing the achievement gap and raising academic achievement for all of his students has had an extraordinarily positive impact on the school community. He also holds leadership roles as Mentor Teacher, Data and Intervention Lead, Teacher Growth and Development Cycle Lead, Math PLC Lead, and as an active member of the Governing Board.

Celzo will join one winner representing each of the 30 MLB clubs to be included in All-Star Week activities and recognized during the pregame ceremony of the 2014 MLB All-Star Game next Tuesday, with pregame ceremonies beginning at 4:30 p.m. PT on FOX from Target Field in Minneapolis. Guests and fans can visit AllStarTeachers.com and ABullsEyeView.com/Baseball for updates and behind-the-scenes access to campaign activities leading up to the All-Star Game.
