Matt Duffy is listed at 6'2", 170 pounds.
He doesn't look like a guy who can hit for power, but he certainly has some pop.
On Tuesday, the 24-year old hit a two-run shot to center field, his third home run in 110 at-bats this season.
"He (Duffy) has really strong hands," Giants broadcaster Mike Krukow explained on KNBR 680-AM Wednesday morning. "This guy is gonna fill out, his frame can hold another 20 pounds. When he gets to be 190 pounds, you might think of him as a guy who can you give you 20 home runs."
The Giants selected Duffy in the 18th round of the 2002 MLB Draft out of Long Beach State.
In 2013, he hit four home runs for Single-A Augusta, and five home runs for Single-A San Jose.
In 2014, he hit three home runs over 97 games with Double-A Richmond, before surprisingly getting called up to the Giants in August.
With San Francisco, he hit .267 with no home runs and eight RBI in 34 regular season games, and only got six at-bats in the postseason.
Duffy was not considered a lock for the 2015 Opening Day roster, but after hitting .361 with three home runs and 15 RBI in spring training, he got the nod.
"I don't know what else he can do," Bruce Bochy said at the time.
The Giants planned to use Duffy as a utility-man, but as Casey McGehee continued to struggle, Duffy continued to get starts at third base.
And he continuously delivered.
Eventually, Duffy forced the Giants' hand, and on Sunday morning, McGehee was designated for assignment.
I just want Duffy to know he has nothing to feel bad about," McGehee told reporters. "He’s doing his job, he’s doing it well, and you know, the rest of it I’ll leave between us. But basically I wanted to make sure that he knew he has absolutely nothing to feel bad about.
“He should be proud that he forced the issue to the point where you’ve got to get him on the field. That’s what his job is. That’s what he’s supposed to do.”
On Tuesday, McGehee accepted his assignment and reported to Triple-A Sacramento.
McGehee could return to the Giants down the road, but Duffy is now the everyday third baseman.
“As his playing time has picked up, he’s playing well,” Bochy said on Sunday. “Last year he handled himself so well with everything we threw at him. This is a tough kid that’s doing very well. I think he’s earned this playing time, to be honest.”
"The thing that is so key about Duffy, is that none of this is surprising him," Krukow declared. "He expects this. When people say that he can't do anything, he has this little look on his face and he kind of takes it as a challenge. I think this guy is gonna be a really good story as the years unfold and he develops more strength upper body.
"He's a threat. And what I like about him is he thinks well within the game. He thinks well within an at-bat. If he gets three at-bats against the same pitcher, that third at-bat he's tough, he has got a plan, and he's disciplined to stay with the plan ... he's a big-league hitter and a lot of it has to do with what's between his ears. This may surprise a lot of people, but it's not surprising Matt Duffy."
