SF Giants: Three biggest surprises from the first half of 2021

Perhaps, the biggest surprise of the first half of the season is that the SF Giants have the best record in baseball at 57-32. However, that would be too easy of a choice. It is not just the record, but how they got to that record that stands out.

SF Giants: Three biggest surprises from the first half of 2021

1. The starting rotation has the third-best ERA in baseball

When the 2020 season ended, the front office was tasked with rebuilding the starting rotation on the fly. Johnny Cueto and Logan Webb were the only incumbents and both were coming off of disastrous seasons. To put it differently, there was a lot of work to be done.

The Giants got started by issuing a one-year, $18.9 million qualifying offer to Kevin Gausman, which he accepted. Then, they dished out a trio of one-year, pillow contracts to Anthony DeSclafani, Alex Wood, and Aaron Sanchez. On top of this, Sammy Long was reeled in on a minor-league pact with an invite to spring training.

There was plenty of risk with this approach. DeSclafani and Wood battled ineffectiveness as well as injuries in 2020, whereas Sanchez missed the entire year as he recovered from shoulder surgery.

This was a strategy that could have fell flat on its face. Some of that risk came to fruition as many Giants starters have spent time on the shelf in 2021, but as a unit, they have been one of the best in baseball. The starting rotation has combined to post the third-best ERA in baseball at 3.18, behind only the New York Mets (2.98 ERA) and the Los Angeles Dodgers (2.94 ERA).

Kevin Gausman was the ace of the rotation in 2020 and he has elevated his status in 2021 to one of the best pitchers in baseball. On the year, he has registered a 1.73 ERA and a 4.43 SO/W ratio across 114.2 frames while earning a National League All-Star bid.

Behind Gausman, DeSclafani has emerged as a formidable No. 2 option, pitching to the tune of a 2.68 ERA in 107.1 innings. The right-handed hurler did not earn an all-star bid and that decision remains questionable.

Aside from these two pitchers, Wood, Sanchez, and Cueto have all put together quality innings when healthy. In the case of Sanchez, he has not pitched since the beginning of May as he has battled bicep tightness and a blister. In comparison to Sanchez, Wood and Cueto have been more durable, giving the Giants 15 and 14 starts, respectively.

Like the three mentioned above, Webb has spent time on the injured list. That said, it does feel like he has taken the next step in his development. When healthy, the 24-year-old has racked up high strikeout totals, induced plenty of weak contact, and he has demonstrated improved command. It has been a really encouraging first half for Webb.

As a whole, the starting rotation has performed well and that is probably the most surprising part of this season. However, it is far from the only surprising part.

2. Improved defense

Anyone who watched the Giants play in 2020 saw a team that struggled badly on defense. Perhaps, the biggest contributor was just the unique circumstances of the pandemic-shortened season. Teams did not have enough time to prepare for the year, and the Giants looked rusty in the field right out the gates.

The 2021 season has been a different story entirely. The SF Giants have brought in plenty of bat-first players in recent years who had experience at multiple positions. Defensive acumen was not necessarily a primary concern in the decision-making process.

Nevertheless, the Giants are grading out nicely according to the defensive metrics. In terms of Outs Above Average (OAA), the Giants have been worth 28 OAA, which ranks as tied for first with the Tampa Bay Rays. Furthermore, they have been worth 30 Defensive Runs Saved (DRS), ranking as seventh-best in baseball.

It is truly a stark contrast to just a couple of seasons ago when San Francisco had one of the worst defensive outfields in baseball. Of course, the emergence of Steven Duggar has solidified the outfield as a defensive force along with Mike Yastrzemski and LaMonte Wade Jr. That issue has resolved itself with better personnel, whereas the infield has always had plenty of strong defenders like Brandon Crawford, Evan Longoria, Brandon Belt, and Buster Posey.

What is causing the Giants’ defense to perform so well? It certainly has to do with instincts, range, and speed of many of the players, but positioning and shifting have to be a factor as well

The starting rotation has excelled at inducing ground balls, and the defense has done well to convert many of those ground balls into outs. Ground balls can sneak through the infield, but it seems as if every ground ball finds a glove that results in an out.

It is fair to say that few expected the Giants’ defense to perform as well as it has and the defensive metrics agree. It might be too early to talk about regular season awards, but Brandon Crawford has made a strong case to earn his fourth National League Gold Glove Award at shortstop. At 34 years old, he is doing what no one expects a player of his age to do at a premium position and that is a bit of a microcosm of the Giants defense as whole.
