Duffy will start at third base for a third straight time Thursday. Duffy looks to be moving into an everyday role at third base for the Giants. He's in the lineup again Thursday, batting eighth, while Casey McGehee will once again sit. Duffy hasn't been spectacular offensively, but has put together a solid .263/.306/.351 batting line thus far, which is better than his counterpart.

Duffy is in the lineup Friday against the Angels, MLB Network Radio reports. With Joe Panik hitting poorly against lefties, Duffy is in the lineup against the Angels left-handed starter C.J. Wilson. Duffy is 11-for-46 (.239) with seven RBI on the season, and is just 3-for-17 (.176) against lefties.

Duffy went 2-for-6 with a double and a pair of RBI in Thursday's extra-inning loss to the Diamondbacks. Duffy got another start at third base in place of the injured Casey McGehee (knee). McGehee did make an appearance as a pinch-hitter and could be back in the lineup Friday, which would push the hot-hitting Duffy back to the bench. It would be hard for manager Bruce Bochy to keep Duffy's bat out of the lineup card, especially with how anemic the Giants' offense has been this season, but he simply doesn't have a place to play him once McGehee is back. Duffy did shag some fly balls in the outfield during spring training, but that seems like an unlikely scenario given his lack of experience at the position.

Duffy started at third and batted second for the Giants on Wednesday, going 1-for-4 with his first career home run in the loss to the Rockies. Duffy has been seeing regular playing time with Casey McGehee (knee) sidelined and has gone 4-for-17 (.235) with a homer and three RBI. McGehee was available to pinch-hit Wednesday and should be back in the lineup soon, which would effectively push Duffy back into a bench role.

Duffy started his second consecutive game at third Monday, going 1-for-3 with a walk in the loss to the Rockies. With Casey McGehee (knee) sidelined, it has been Duffy - and not Joaquin Arias - who has been getting the playing time at the hot corner. It seems like the Giants are trying to get Duffy's bat in the lineup anyway they can after a torrid spring (.361/.400/.639). McGehee isn't expected to go on the DL, so this recent string of playing time may come to an end sooner rather than later.

Duffy will start getting work at first base, and he could get a start at the position Saturday against the Padres, CSN Bay Area's Alex Pavlovic reports. Duffy's stint at first base probably wouldn't last long, as the Giants hope to have Brandon Belt (groin) available by Monday, and haven't even ruled him out for the upcoming weekend. While Duffy thus seems unlikely to add first-base eligibility within the next week or two, he could eventually log enough games at the position to qualify.

Duffy started at second base Wednesday, going 2-for-4 with a double and an RBI in the win over the Diamondbacks. Manager Bruce Bochy gave Joe Panik the night off, affording Duffy the chance to make his first start of the 2015 season. He played his way on to the 25-man roster this spring with an impressive .361/.400/.639 slash line and has kept it going into the regular season with three hits in five at-bats. He will be limited to a start or two per week, but could become fantasy relevant if any of the Giants' middle infielders go down to injury.

Duffy officially made the Opening Day roster, CSN Bay Area reports. Duffy was expected to start the year in the minors, but his slash line of .361/.400/.639 this spring forced management's hand. He beat out Ehire Adrianza for the final utility spot, and he has been taking fly balls in the outfield to add to his already versatile position eligibility. A doubles hitter with speed, Duffy could be a fantasy relevant player with regular playing time, but the Giants would have to be struck by injury for him to get that opportunity early in the year.

With it looking like Travis Ishikawa (back) will start the year on the DL, Duffy has a strong chance of making the Opening Day roster, Andrew Baggarly of the San Jose Mercury News reports. Manager Bruce Bochy announced that the disabled list was a "strong possibility" for Ishikawa, and this would allow Duffy to make the 25-man roster to start the season. Duffy has had a strong spring, batting .385 with three homers. He likely won't see regular playing time with Joaquin Arias and Ehire Adrianza both making the squad, but he would all of a sudden become an intriguing option in deeper leagues should any of the Giants' infielders go down with an injury.

Duffy is batting .385 with a three doubles, a triple, a home run, and four RBI this spring. Duffy is putting pressure on the Giants to earn one of the 25 Opening Day roster spots with his strong play this spring. He has always been able to put the bat on the ball (.304 average through 3 minor league seasons) and has decent speed on the base paths (20 stolen bases at Double-A Richmond last season). The issue for Duffy is that there simply aren't enough bench spots left for another middle infielder. Veteran Joaquin Arias has already locked up a utility role and the Giants prefer Ehire Adrianza's glove to Duffy's. Also working against Duffy is the fact that he does have minor league options available, whereas Adrianza is currently out of options. Duffy should start the year at Triple-A Sacramento and be the first middle infielder called up when the situation arises.
