Matt Kemp took Jeff Samardzija deep on Saturday. In the third inning of a game played at Petco Park, the San Diego Padres outfielder deposited a slider from the San Francisco Giants righty over the left field wall. According to ESPN Home Run Tracker, the blast traveled 398 feet.

As you might expect, Samardzija wasn’t pleased with the pitch. He doesn’t feel the location was terrible, and “Shark” has a solid slider, but he regrets not throwing a sinker. He explained why prior to last night’s game at Fenway Park.

Samardzija on facing Matt Kemp on July 16, 2016: “I walked the first two guys in the first inning. Kemp came up, hitting in the three-hole, and I struck him out on five pitches. Four of the five were sinkers in that he mostly swung through. One of them he fouled off and then he struck out swinging.

“Third inning, he came up again with no one on. I threw him a slider 0-0 and he took it for a ball. I decided to throw it again on 1-0 and he hit a homer.

“When I look back at games, that’s the type of thing I remember. It stands out boldly. I’m thinking to myself, ‘We just had success doing one thing and I did something else.’ The old adage is that you don’t change. You don’t take unnecessary risks.

“In one respect, it wasn’t a bad pitch. It was a strike slider. The first one was under the zone, then the second was bottom of the zone and he hit it. But there was no reason for me to change. Now, if he’d have taken the fourth sinker down and in that I threw him in the first inning, and hit it for a double down the line, then you’re thinking to yourself, ’OK, let’s go to another spot; let’s go up on the hands or slider away.’ But until someone proves to you that they can hit something, why not stay there?

“Sometimes you overthink. You give too much credit to guys or you overthink a situation. I probably told myself, ‘OK, I’ve thrown him five sinkers in, so he’s thinking sinker in; let’s go to something different.’ Well, I should have stopped myself there. I should have told myself, ‘OK, he can still be looking in, but it doesn’t matter, because he didn’t hit it the first time.’

“I don’t remember exactly what happened his third time up. It was probably nothing, otherwise I’d remember. [Kemp grounded weakly to third.] But I probably didn’t throw him another slider. If I did, it was probably in the other batter’s box.

“Had I looked at (the scouting data on Kemp)? The 70 pages of information you can look at? No. I’ve probably faced him a dozen times already this year. I have a good idea of what he can and can’t hit. But you have brain farts in this game. You have momentary lapses. That what happened and I gave up a home run.”
