Kemp's impact will be missed by Dodgers

Matt Kemp was just the third player to bat .400 with 10+ HR and 25+ RBI in April, joining Larry Walker in 1997 and Tony Perez in 1970.

The Los Angeles Dodgers placed Matt Kemp on the 15-day disabled list with a strained left hamstring after Monday night's game against the Arizona Diamondbacks, and Kemp's absence will certainly be felt offensively.

Kemp saw his MLB-leading active streak of 399 games played come to an end Monday, and while his production decreased this month, his early-season performance was impressive. His 12 home runs by April 30th were the fifth-most in MLB history, and according to Elias, was just the third player since 1920 (when RBI became official) to hit .400 with 10+ HR and 25+ RBI in April (excluding any March games).

Without Kemp, the Dodgers also lose one of the best high-ball hitters in baseball. Kemp is 11-for-21 (.524) against high pitches in 2012, tied with Ryan Sweeney for the best batting average on such pitches in baseball entering Tuesday.

Highest 2012 BA Against High Pitches

For all of these reasons and more, Kemp has been one of the most valuable position players in baseball over the last two seasons. Using the Baseball Reference metric “Wins Above Replacement,” Kemp is second in the National League and fourth in Major League Baseball in WAR since the start of the 2011 season. Only Dustin Pedroia, Ben Zobrist and Ryan Braun have a higher WAR than Kemp in that span.

Kemp, however, did see his production trail off drastically in May. During this month, Kemp was batting just .212 in 11 games and had not gone deep. The difference has primarily come against the fastball. During April, Kemp batted .465 against the heater with nine home runs. In May, that average dipped to .250. His strikeout percentage against the fastball also jumped significantly, increasing from 11.3 percent in April to 28.6 percent in May.
